Description

  The present invention relates to a fee-type rice milling facility for processing rice grains such as rice bran and brown rice brought by a user.

  In Patent Document 1, in a fee-type rice milling facility equipped with a stone removing device, when it is detected that the amount of brown rice supplied to the rice milling machine has decreased at the end of the work, the stone removing operation of the stone removing device is performed. There is a description of a stone removal residual rice treatment process in which the foreign matter discharge port of the stone removal device is opened continuously and the stone is discharged only for a certain period of time, and then the residual brown rice is supplied to the rice mill.

  However, since the stone extraction device is configured to perform specific gravity selection by a rocking sorter that is driven to swing up and down obliquely and has a vent hole, a predetermined grain layer is required for this sorting work, but the work ending process In this case, since this grain layer is not sufficiently secured, not only the sorting accuracy is bad, but also a long working time is required. In order to shorten this time and to prevent foreign matters such as stones from being mixed, a remaining rice treatment process has been set up. In the foreign matter discharged from the stone remover, a small amount of brown rice, for example, 30 kg of brown rice is polished at about 500 g. The amount of white rice received by the user during the milling of 2 to 3 kg of brown rice is inevitable.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a process diagram of a charge-type rice milling facility. The brown rice put into the charging hopper 1 is fed to the first elevator 2 by the first rotary valve 9, and the stone is transferred from the first elevator 2 to the stone. It is supplied to the punching device 4 for processing. Then, the stone removed by the stone removing device 4 is supplied to the second elevator 5 through the brown rice passage 10 and the remaining rice passage 11 and is transported to the storage hopper (brown rice tank) 12 by the second elevator 5. . The brown rice stored in the storage hopper 12 is sequentially fed to the rice mill 6 by the second rotary valve 13, subjected to whitening processing by the rice mill 6, and discharged to the white rice tank 14.

  A grain presence / absence detection sensor 15 that detects the presence / absence of grain (brown rice) to be thrown in is provided in the lower portion of the throwing hopper 1. In addition, in the feeding hopper 1 slightly above, a grain amount sensor 7 is provided which is a brown rice amount judging means for judging whether or not the amount of grain put in at the start of operation is equal to or less than a predetermined amount. The grain amount sensor 7 is specifically a pressure-sensitive grain presence sensor, and is provided at a height position corresponding to a capacity of 2 kg in the charging hopper 1.

  The transfer path from the first elevator 2 to the stone remover 4 is provided with a switching valve 8 serving as a supply switching means, and a passage 16 for supplying the unpolished rice discharged from the first elevator 2 to the stone remover 4 and the second elevator 5 can be switched to the passage 18 to be supplied to 5.

  As shown in FIG. 4, the stone remover 4 is constructed by oscillating a sorter 3 that is driven by a oscillating drive device 19 to form a vent hole with a high inclination on one side, and the specific gravity while shaking the brown rice supplied from above. It is what is selected. Due to this rocking action, stones with a high specific gravity sink downward and are sent to the upper part of the rocking sorter 3 and discharged to the foreign material discharge path 21, and the brown rice with a low specific gravity flows down and discharged to the hopper 22. Then, it is supplied to the second elevator 5 through the brown rice passage 10. The foreign matter discharge path 21 is inclined to one side and is provided with a valve driven by a solenoid 23 at the end thereof so that the foreign matter can be discharged to the lower discharge path 24. The discharge passage 24 is provided with a switching valve 25 so that it can be switched to the outside of the machine and to the remaining rice passage 11 described above. Reference numeral 20 denotes a blower fan, and reference numeral 26 denotes a receiving hopper of the stone remover 4. A check lid 27 detachably attached to the hopper 26 is provided with a magnet separator 28 for removing mixed metal. The magnet separator 28 can be mounted in the flow direction and perpendicular direction of the brown rice to improve the metal removal rate. If the one side 29 of the receiving hopper 26 is opened, the magnet separator 28 has a lot of metal. Even if it adheres, the brown rice flows smoothly. Further, if the vent hole in the portion corresponding to the swinging sorter 3 where the brown rice falls directly is located below the receiving hopper 26, the sawdust and the like are not clogged.

  In FIG. 1, an operation unit 30 is provided between the charging hopper 1 and the white rice tank 14, 31 is an operation procedure table for the user, 32 is a whiteness selection switch, and 33 is a charge input port. As shown in FIG. 1, the fee-type rice milling facility is separated by a partition wall 36 into a guest room 34 where a user works and a machine room 35 where each work machine is installed.

  Next, the work process will be described with reference to FIGS. 5 and 6. The user inputs a fee according to the instructions in the procedure table 31, and then inputs brown rice into the input hopper 1 and sets the milling degree selection switch 32. .

  When both the grain presence / absence detection sensor 15 and the grain quantity sensor 7 detect grain, the quantity of input grain is determined by the predetermined amount, that is, 2 kg or more by the brown rice quantity judgment means 7, Work and rice milling work. That is, the first rotary valve 9, the first elevator 2, the stone removing device 4, the second elevator 5, the second rotary valve 13, and the rice mill 4 are respectively set at predetermined timings by the input of the sensors 7 and 15 and the charge. The drive is started and stone removal work and milling work are performed. At this time, the switching valve 8 is positioned so that brown rice can be supplied to the passage 16 side.

  Next, when the lower grain presence sensor 15 detects that there is no grain when the lower grain presence sensor 15 is OFF, the process proceeds to an end operation step, and after a predetermined time has elapsed, the first rotary valve 9 and the first elevator 2 stop. Next, the solenoid 23 is operated to discharge the foreign matter in the foreign matter discharge path 21 from the lower discharge path 24 to the outside of the machine. Further, after a predetermined time, the recovery rate of the brown rice is increased by switching the switching valve 25 of the discharge passage 24 and returning the remaining rice to the rice mill 4 through the remaining rice passage 11. Next, at a predetermined timing, driving of each part such as the stone removing device 4, the second elevator 5 and the rice milling machine 6 is stopped, and the operation is finished.

  When the grain presence / absence detection sensor 15 detects the grain and the grain amount sensor 7 does not detect the grain, the amount of input grain is determined by the brown rice amount determination means 7 as a predetermined amount, that is, 2 kg or less. . In this case, the switching valve 8 is switched so that the brown rice supplied from the first elevator 2 is guided to the passage 18, bypasses the stone remover 4, and is supplied directly to the rice mill 6 via the second elevator 5. Switch.

  Each part is driven in this state, and the rice milling work is performed. That is, the brown rice in the charging hopper 1 is supplied to the first elevator 2 by the rotary valve 9, and further guided to the passage 18 side by the switching valve 8, and then polished through the second elevator 5, the hopper 12, and the second rotary valve 13. It is sent to the machine 6 and the rice milling work is performed.

  Thus, when the amount of input grains (brown rice) is determined to be extremely small by the brown rice amount determination means 7, the usual stone removal process and By eliminating the remaining rice treatment process, it is possible to reduce long-time work and brown rice loss caused by these processes, and eliminate the feeling of reduced white rice received by the user.

  It should be noted that the brown rice amount determination means can be determined based on the input fee instead of the grain amount sensor, that is, the stone removal process is not performed when the minimum fee (100 yen) is input. A weight meter may be provided in the hopper 1 to determine the amount of brown rice introduced.
